4 bolts, 5 minutes, and if you have nozzles, make sure the new one has/doesn't have them and take things off accordingly. If it doesn't, take off the hoses then unclip the nozzles. Clip them into the new one, bolt it on, add hoses...done! (make sure it's lined up right too)

It takes two people to install a hood. Once the old hood is removed, grab the new hood and orient it upright over the engine; like you just opened an attached hood. With one hand at the back corner, use your opposite shoulder to support the front of the hood. You can then use your free hand to screw in the bolts. Shift the hood such that the bolts line up with the old paint marks, and tighten the bolts; this is a good starting point.

With the striker removed from the new hood, close the hood and check your gaps. Check the front to back spacing of each side, as well as the gap width on each side. Slightly loosen the hood bolts and adjust as necessary. This is the hardest part in changing a hood; there are alot of tricks of the trade, too much to mention here.

Once the new hood is aligned, attach the striker to the hood. Again align the bolts with the old markings, as you did with the hood bolts. THIS IS VERY IMPORTANT. You want to tighten striker bolts just enough that it doesn't slide around on its own, but if you tap the striker it will move alittle. This way when you close the hood it will center itself with the latch. IF YOU FAIL TO DO THIS CORRECTLY IT COULD BE A REAL PAIN TO OPEN THE HOOD. I have been there, and you don't want to be. With the hood closed the striker will align itself with the latch. Pop the hood, and completely tighten the striker bolts, being careful not to let it slide as you tighten it.
